CHARLES L. THOMAS, OF JANESVILLE, WISGONS1N.

VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 258,823, dated May 30, 1882. Application filed November 26, 1881. (Model) To all whom it may concern:

Be it known that I, OHARLEs L. THOMAS, a citizen of the United States, resident of J anesville, in the county of Rock and State of Wiscousin, have invented a new and valuable Improvement in Wagon-Springs; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a bottom view of my invention. Fig. 2 is a cross-section, and Fig. 3 is a perspective detai This invention has relation to the springconnections between the bars of the runninggear and the body of the wagon; and it consists in the construction and novel arrangement of the two-branched spiral springs, having end arms secured to the body-sills and the pivoted arms extending inward from the side bars and connected to the springs between the branches, as hereinafter set forth, and especially pointed out in the claims appended.

In the accompanying drawings, the letter A designates the side bars of the wagon, and B the body-sills or bottom framing of the body.

(J indicates the two-branched spiral springs, of which four are usually employed, attached near the ends of the body on opposite sides thereof. Each spring 0 consists of two spiral branches, D D, each having an end arm, 0, extending outward from the spiral to the marginal frame-work B of the body, and secured thereto by means of a screw or bolt, 1), passing through a terminal eye, 0. These arms or extend inward from the s'ills B, so that the springs are under the body, the spiral branches being turned downward or below the plane of" arms E. The arms E serve to connect the springs to the side bars and support the body. They are made of metal, and are pivoted to hangers 70, secured to the side bars by means of pivot-bolts 1. Each arm is connected to a spring, 0, between its spiral branches, as above set forth. The arms connected to the front springs are usually provided with outward extensions 1n beyond the side bars, supporting steps a. The branch spirals ot' the springs O are on each side of the arm E, and each spiral is secured to the body at the outer end or arm, a. In this manner it is designed to avoid end pitch. As the spring is free from any bearingin connection with the body in its middle portion, it gives inward readily as the arm E comes down under pressure. The arrangement of the springs well under the body of the wagon puts them practically out of si ght.

A spring for buggies, seats, &c., consisting of a single perpendicular coil formed near the center of a bar or rod of steel, the two projecting ends of which, extending in the same direction, form an upper arm, (the end of which is shaped at an angle into a rest for the "box or seat,) and a lower arm, longer than the upper arm and bent near the end to a perpendicular elbow, andupon the end having ears for attachment to the clip-ties, is not new.

A vertical standard secured to the side bar of a vehicle has been surrounded by a coiled spring resting on'a. shoulder at the bottom of the same, anda thimble which rests over thestandard and incloses the spring has been provided with a lug, to which a horizontal arm having a transverse thimble at its outer end has been pivoted, has been used in connection with two coiled springs on ashaft, one on each side of the transverse thimble,,their inner ends being connected to the transverse thimble and their outer ends to lugs or plates, which hold the shaft and prevent it from turning. This con struction is not claimed herein, and protection only is asked for what is hereinafter claimed.
